2 Claims. (Cl. 131-173) This invention relates to a smoking pipe of the water reservoir type.

An object of the present invention is to provide a smoking pipe of the water reservoir type in which the lighted tobacco is not wetted upon any accidental blowing of exhaled gases by the user into the bit of the pipe.

Another object of the present invention is to provide a smoking pipe of the Water reservoir type which effects a quick cooling of the smoke and ready condensation and deposition of tar particles before it enters the pipe stem.

These and other objects and advantages of the present invention will be fully apparent from the following description when taken in connection with the annexed drawing, in which:

Figure 1 is an isometric view of the smoking pipe according to the present invention;

Figure 2 is an isometric exploded view of the assembly shown in Figure 1;

Figure 3 is a partial sectional view on an enlarged scale, taken on the line 3-3 of Figure 1, showing the path of tobacco smoke drawn from the bowl into the body of the pipe and through the pipe stem;

Figure 4 is a fragmentary sectional view, on an enlarged scale, taken on the line 4-4 of Figure 3; and

Figure 5 is a fragmentary sectional view showing the path of exhaled gases or air accidentally blown by the user through the bit of the pipe.

Referring in-greater detail to the drawing in which like numerals indicate like parts throughout the several views, a smoking pipe according to the present invention comprises an upstanding body 10 having an open top as at 12 in Figure 2, and a hollow open ended tubular member 14 positioned in at right angles to the body 10. One end of the tubular member 14 is in communication with the interior of the body 10.

A hollow pipe stem 16 having a closed end 18 and an open end 20 is fixedly positioned within the tubular member 14 so that the portion adjacent the closed end 18 is within the interior of the body 10, inwardly of and spaced from the end of the tubular member 14 which is in communication with the interior of the body 10.

An upstanding conduit 22 is positioned within the body 10 and has the lower end thereof reduced in diameter as at 24 and extending through a bore provided in the side of the pipe stem 16 adjacent the closed end 18, the interior of the conduit 22 being connected in communication with the interior of the pipe stem 16. The upper end of the conduit 22 is adjacent to and spaced below'the open top of the body 10, as shown in Figures 3 and 5.

A tobaccoreceiving bowl 26 is positioned above and over the open top 12 of the body 10. An externally threaded ring 28 is secured to the body 10 at the open upper end of the latter and forms a means by which the bowl 26 is connected to the body 10, there being provided on the exterior of the bottom of the bowl 26 a metalhc linear element 30, CUP-$11 1 and having an internally threaded depending skirt 32 threadedly receiving the threaded upper portion of the ring 28 for securing the pipe bowl 26 to the body 10.

The underface of the tobacco bowl 26 is spaced from the upper end of the conduit 22 and provides a passageway between the interior of the body 10 and the interior of the conduit 22. a

A vertically disposed smoke discharge tube 34 extends through the bottom 36 of the bowl 26 and has its upper end in communication with the interior of the bowl 26 and has the portion adjacent its lower end within the interior of the body 10. The tube 34 has external threads engaging internal threads provided in a flanged grommet 38 extending through a bore provided in the bottom 36 of the bowl 26, the flange of the grommet 38 being exteriorly of the bowl 26 and on the surface of the'bot-tom 36.

A cup element 40 having a hole 42 extending through the bottom thereof is positioned within the body 10 with the perimeter of the cup element 40 adjacent to and spaced from the lower end of the dischargetube 34 and with the hole 42 in registry with the lower end of the discharge tube 34.

Passage-providing means is provided fixedly securing the cup element 40 in spaced relation with respect to the portion adjacent the lower end of the discharge tube 34. Specifically, this means embodies a plurality of vertically disposed rigid straps 44 (Fig. 4) providing passages for the egress of exhaled gases through the spaces between such straps 44.

The open end 20 of the pipe stem 16 is flush with the end of the tubular member 14 remote from the body 10 and a mouthpiece or bit 46 having a boss of reduced diameter on one end thereof, as indicated by the refer ence numeral 48, is detachably received in the open end of the pipe stem 16. A passage 50 extends longitudinally through the bit 46 and the boss 48 and is in communication with the bore provided in one end of a bar element 52 having an aperture 54 in one end portion in communication with the passage 50 in the bit 46. The bar element 52 has alternatingly arranged spaced disc elements 56 having upper and lower portions broken away to provide a tortuous passage for smoke drawn through the space between the broken away portions of such disc element 56 and the adjacent portion of the inner wall of the pipe stem 16.

In use, a smoking pipe of the present invention is provided with a smoldering charge of tobacco in the bowl 26 in the conventional manner. The smoke is drawn downwardly through the tube 34 into the interior of the body 10, thence through the conduit 22 and through the pipe stem 16 into the passage 50 in the bit 46 to the mouth of the user. The direction of the flow of the tobacco smoke is indicated in Figure 3 by arrows.

An important feature of the present invention is that upon inhaling or drawing of the smoke by the user downwardly through the tube 34, the tobacco smoke behaves like a jet stream and shoots down into the water 58 which is held within the body 10 and does not flow through the passages between the straps 44 which support the cup element 40 in its spaced position deposition of the tar particles that are normally in the smoke.

Another feature of the present invention which is int.-

Patented Ma. 29; 1960* portant is illustrated in Figure 5 in which accidental 12eentry of airbr gases through the passage 50, through the aperture 54 through the pipe stem 16, and upwardly through the conduit 22 into the interior of the body does not result in movement of the water .58 upwardly through the tube 34 to wet the tobacco held in the bowl 26. Such expelled air or gases, caused by the user exhaling through the bit 46 or talking while the bit 46 .is .in his :mouth, follows the path indicated by the arrows through the spaces between the straps 44 which support the cup element 40, and thence upwardly through she interior of the tube 34 to the .interior of the bowl 26, without causing any of the water 58 to flow therealong. This path of airflow saves the charge of tobacco within the bowl 26 from being dampened by water from the body 10.. The water :58 .Within body 10 is preferably kept at a quantity such that the level of the water is slightly below .the perimeter of the cup element 46,, .as shown in Figures 3 to .5, inclusive.

The cup element 40 serves a useful function in that during the smoking of the pipe such element directs inhaled smoke in the form of jet stream to the element hole'42 which is submerged in water, and assists in breaking up surface tension of water as illustrated by the dotted line in Figure 4. Also, actual experiments demonstrated that the force of the inhaled smoke in the :form of jet stream is more concentrated by the presence of the cup element. In the event that expelled air or gases caused bythe user exhaling or talking through the bit while the hit .is .in .his .mouth, the air or gases follow the .path indicated :by the arrows in Figure 5, therebypreventing water from flowing to the bowl or extinguishing "the lighted tobacco.

It is therefore seen that the smoking pipe :of the present invention as heretofore described provides a water reservoir which effects a quick cooling of thesmoke and ready condensation anddeposition of tarparticles in the smoke before the .smoke enters the pipe stem and also enables the lighted tobacco in the tobacco bowl tobe'unaffected by water by any accidental blowing of exhaled gases or air .by the user into the bit of the pipe.
